Top 10 Database Mounting Issues and Their Solutions

Got a problem getting your databases in Exchange 2000 Server and later to mount? There are several conditions that can:

Cause your Exchange databases to not mount, even though the Exchange Information Store service still starts

Prevent the Information Store service itself from starting, which would leave databases unmounted

In most cases, the application log of the server running Exchange provides enough information to continue troubleshooting the problem and find the root cause. Those events are typically logged with a source of either MSExchangeIS (Microsoft Exchange Information Store) or ESE (Extensible Storage Engine).

Find out the how to address these issues, numbered in the order of greatest impact, by reading the Microsoft Knowledge Base articles listed on this page.
